On Friday, March 19, at 7.27 p.m., the NYPD issued a general press advisory, advising that from March 10, 2021 through March 19, six schools in Manhattan were mailed a similar-looking white envelope containing a white powdery substance.
In each instance, the material was screened and determined to be non-hazardous. Each envelope has a U.S. flag stamp and a handwritten address in block letters. The NYPD shared an example of the envelope for public awareness.
New NYC Schools Chancellor, Meisha Porter, had recently written an op-ed about her plans in her new role, and reassured children, parents and teachers about the safety measures taken amid the return to full-time in-person learning.
Anyone with information about these incidents is encouraged to call the NYC Terrorism Hot-Line: 888-NYC-SAFE. Anyone receiving a suspicious package or envelope should call 911.
